the press button needs to be pressed several times before the cistern will flush

I had the same problem. An have it again! Th flush is initiated by a small change in pressure caused by a valve on the back side of the fascia. yu need to call grohe, tell them, get sent a new one, unscrew the little valve casing and put the new one on. v easy.
